#### POST /api/admin/v1/stores/{storeId}/orders/{orderId}/fulfillments

Create a fulfillment (mark items as shipped).

**Request body:**

```json
{
  "tracking_company": "DHL",
  "tracking_number": "1234567890",
  "tracking_url": "https://www.dhl.com/track/1234567890",

    {
      "order_line_id": 301,
      "quantity": 2
    }
  ],
  "notify_customer": true
}
```

| Field | Type | Required | Validation |
|-------|------|----------|------------|
| `tracking_company` | string | No | Max: 255 |
| `tracking_number` | string | No | Max: 255 |
| `tracking_url` | string | No | Valid URL, max: 2048 |
| `line_items` | array | Yes | At least one line item. |
| `line_items[].order_line_id` | integer | Yes | Must belong to this order. |
| `line_items[].quantity` | integer | Yes | Min: 1. Must not exceed unfulfilled quantity. |
| `notify_customer` | boolean | No | Default: true. Sends shipping notification email. |

**Success response:** `201 Created`

```json

  "data": {
    "id": 501,
    "order_id": 50,
    "status": "shipped",

    ]
  }

```

**Error responses:**
- `403` - Insufficient permissions
- `4<truncated omitted_approx_tokens="1873" />
| `credit_card` / `paypal` | Inventory committed (on_hand decremented, reserved decremented) | N/A (already committed) | No inventory change |
| `bank_transfer` | Inventory reserved only (reserved incremented) | Inventory committed (on_hand decremented, reserved decremented) | No inventory change |

For bank transfer orders, inventory is held in a reserved state until the admin confirms payment. If the order is auto-cancelled (see Section 10.8), the reserved inventory is released back.

### 11.7 Auto-Fulfillment for Digital Products

When a payment is confirmed (either instant for credit_card/paypal, or via admin confirmation for bank_transfer):

1. Check if **all** order lines reference variants with `requires_shipping = false` (digital products).
2. If yes: automatically create a fulfillment record covering all order lines:
   - `status = 'delivered'` (skip pending and shipped)
   - `tracking_company = null`, `tracking_number = null`, `tracking_url = null`
   - `shipped_at = now`
   - Set `order.fulfillment_status = 'fulfilled'`
   - Set `order.status = 'fulfilled'`
3. If the order contains a mix of physical and digital products: do **not** auto-fulfill. The admin must create fulfillments manually (they can fulfill digital items immediately and physical items when shipped).

This ensures digital product orders are immediately marked as complete after payment.

### 11.6 Order Export

`GET /api/admin/v1/orders/export` returns a CSV file of orders matching the current filter criteria.

**CSV columns:** `order_number`, `created_at`, `status`, `financial_status`, `fulfillment_status`, `customer_email`, `customer_name`, `subtotal_amount`, `discount_amount`, `shipping_amount`, `tax_amount`, `total_amount`, `currency`, `shipping_method`, `tracking_number`

All monetary values are exported in minor units (cents). Dates use ISO-8601 format. The response uses `Content-Type: text/csv` with `Content-Disposition: attachment; filename="orders-{date}.csv"`.

## 2. Storefront REST API

**Prefix:** `/api/storefront/v1`
**Middleware:** `store.resolve`, `throttle:api.storefront`
**Content-Type:** `application/json`

These endpoints power the interactive storefront experience (cart drawer, checkout flow, search autocomplete, analytics).

---

### 2.1 Cart Endpoints

#### POST /api/storefront/v1/carts

Create a new cart.

- **Authentication:** None (guest) or session-based (logged-in customer)
- **Rate limit:** `api.storefront` (120/min per IP)

**Request body:**

```json
{
  "currency": "EUR"
}
```

| Field | Type | Required | Validation |
|-------|------|----------|------------|
| `currency` | string | No | Valid ISO 4217 code. Defaults to store's `default_currency`. |

**Success response:** `201 Created`

```json
{
  "id": 42,
  "store_id": 1,
  "customer_id": null,
  "currency": "EUR",
  "cart_version": 1,
  "status": "active",
  "lines": [],
  "totals": {
    "subtotal": 0,
    "discount": 0,
    "total": 0,
    "currency": "EUR"
  },
  "created_at": "2026-02-11T10:00:00Z",
  "updated_at": "2026-02-11T10:00:00Z"
}
```

**Error responses:**
- `422` - Validation error (invalid currency)

---

#### GET /api/storefront/v1/carts/{cartId}

Retrieve a cart with all lines and computed totals.

- **Authentication:** None (cart ID acts as token)
- **Rate limit:** `api.storefront` (120/min per IP)

**URL parameters:**

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `cartId` | integer | Yes | The cart identifier |

**Success response:** `200 OK`

```json
{
  "id": 42,
  "store_id": 1,
  "customer_id": null,
  "currency": "EUR",
  "cart_version": 3,
  "status": "active",
  "lines": [
    {
      "id": 201,
      "variant_id": 101,
      "product_title": "Classic T-Shirt",
      "variant_title": "Blue / Medium",
      "sku": "TSH-BLU-M",
      "quantity": 2,
      "unit_price_amount": 2500,
      "line_subtotal_amount": <truncated omitted_approx_tokens="1662" />a rate limit is exceeded, the server returns `429 Too Many Requests`:

```json
{
  "message": "Too many requests. Please try again later.",
  "retry_after": 42
}
```

**Headers included on all rate-limited responses:**

| Header | Description |
|--------|-------------|
| `X-RateLimit-Limit` | Maximum requests allowed in the window |
| `X-RateLimit-Remaining` | Requests remaining in the current window |
| `Retry-After` | Seconds until the rate limit resets (only on 429) |

### Per-Endpoint Rate Limit Mapping

| Endpoint Group | Tier |
|---------------|------|
| `POST /admin/login` | `login` |
| `POST /account/login` | `login` |
| `POST /api/storefront/v1/carts*` | `api.storefront` |

[172] assistant: The REST acceptance pass found that Laravel’s API stack was stateless while these endpoints intentionally support session customers and session-keyed checkout throttling. The storefront API now starts a secure session, returns documented 422 validation for invalid/cross-store variants and inventory, and accepts the documented cart-version field. All 9 API scenarios now pass with 129 assertions.

[172] assistant: The REST acceptance pass found that Laravel’s API stack was stateless while these endpoints intentionally support session customers and session-keyed checkout throttling. The storefront API now starts a secure session, returns documented 422 validation for invalid/cross-store variants and inventory, and accepts the documented cart-version field. All 9 API scenarios now pass with 129 assertions.

# Shop Implementation Progress

Last updated: 2026-07-12

## Mission

Build the complete self-contained multi-tenant shop described by Specs 01-09 from the clean Laravel starter on branch `2026-07-12-codex-gpt-5-6-sol-ultra`. No implementation from another branch will be reused.

## Delivery Status

| Phase | Status | Verification |
| --- | --- | --- |
| 0. Specification traceability and repository audit | Complete | Specs and starter audited by backend, frontend, and QA roles |
| 1. Foundation, tenancy, authentication, authorization | Complete | All migrations pass; tenancy/auth infrastructure and factories are present |
| 2. Catalog, inventory, collections, media | In progress | Schema/models/factories/demo catalog complete; behavior tests pending |
| 3. Themes, CMS, navigation, storefront shell | Complete | Blade compilation, Vite build, and live Herd render smoke pass |
| 4. Cart, checkout, discounts, shipping, taxes | In progress | Customer UI and services integrated; full Pest/Chrome flow pending |
| 5. Payments, orders, refunds, fulfillment | Pending | Pest unit/feature + Chrome |
| 6. Customer accounts | Pending | Pest feature + Chrome |
| 7. Admin panel | Pending | Pest feature + Chrome |
| 8. Search, analytics, apps, webhooks | Pending | Pest unit/feature |
| 9. Accessibility, responsive, dark mode, error states | Pending | Build + Chrome review |
| 10. Full quality and acceptance verification | Pending | Pint, quality checker, all Pest, fresh seed, routes, config cache, Chrome |

## Iteration Log

### Iteration 0 - Audit and planning

- Confirmed the current branch contains only the Laravel 12 / Livewire 4 starter plus specifications.
- Confirmed no shop implementation is present in the working tree.
- Loaded the required in-app Chrome acceptance workflow and Laravel deterministic quality workflow.

###<truncated omitted_approx_tokens="948" />d at `app/Actions/SanitizeHtml.php`.

**Allowed HTML elements and attributes:**

| Element | Allowed Attributes |
|---------|-------------------|
| `p`, `br`, `strong`, `em`, `u` | none |
| `ol`, `ul`, `li` | none |
| `a` | `href` |
| `img` | `src`, `alt` |
| `h1` through `h6` | none |
| `blockquote` | none |
| `table`, `thead`, `tbody`, `tr`, `th`, `td` | none |
| `div`, `span` | none |

All other elements and attributes must be stripped. Empty elements should be removed.

**Where sanitization is applied:** Before persisting product `description_html` and page `body_html` fields. The sanitization runs during the create and update operations for these models.

---

### 4.6 SQL Injection Prevention

**Requirements:**

- All database queries must use Eloquent ORM with parameterized bindings (Laravel default behavior).
- No raw query strings may contain unsanitized user input.
- Any use of `whereRaw`, `selectRaw`, or `DB::raw` must use parameter bindings (the `?` placeholder syntax).
- FTS5 (full-text search) queries require special handling: user input must be sanitized before building the MATCH expression.

#### FTS5 Input Sanitization

Before using user input in an FTS5 MATCH expression:

1. Strip all characters that are not Unicode letters, Unicode numbers, or whitespace (remove FTS5 special operators like `*`, `AND`, `OR`, `NOT`, `NEAR`, quotes, parentheses, etc.).
2. Trim leading and trailing whitespace.
3. Pass the sanitized string via a parameterized binding (never concatenate into the query string).

---

### 4.7 Mass Assignment Protection

**Requirements:**

- Every Eloquent model must define a `$fillable` array listing only the columns that are safe for mass assignment.
- The pattern `$guarded = []` is never permitted in any model.
- All controller and Livewire action code must use `$request->validated()` (not `$request->all()` or `$request->input()`) when passing data to model creation or update methods.
